FYI R7000 105 CS-HG700 11-34 cassette
I spent a couple hours going in circles after moving a new bike's 105 11-34 cassette to a different rear wheel. I didn't realize there was a spacer ring on the original wheel hub. As a result the cassette wasn't tight enough and the rear derailleur shifting was totally wacky. It wasn't until I used a micrometer to measure the hub length on both rear wheel hubs that I found the spacer. So if you try and install a CS-HG700 11-34 cassette on a road hub you need the spacer (same size as 10 speed). If you install the cassette on a mountain bike hub you don't use the spacer. I think this is the only Shimano cassette like this. I think the new 8000 Ultegra 11-34 is normal.

Yes...
A feature that Shimano introduced with the large sprocket cassettes allowing them to be used on 10s hubs.
And, most MTB freehubs still use 10s compatibility.

CS HG800 cassettes have an additional spacer also. Pictures are included in this thread:
